44 automated checks across tags, triggers, variables, Consent Mode v2, and security & governance — the scan a senior GTM consultant runs on engagement day one. Shadow-workspace only. Never mutates your live container.
Redacted from a real container. One critical security flag, five warnings, 5 passed — each with a one-click fix path. Fixes land in a sandbox copy of your container — your live tags are never touched until you publish.
Five marketers, three agencies, two years later — your container has 40 tags, 15 unused, and a custom HTML nobody remembers approving. We find what shouldn't be there.
A GTM audit alone catches container-level bugs. Pair it with a GA4 audit and we add a 6th Integration chapter with 3 cross-checks that catch the bugs living between the two products — the ones that silently corrupt your revenue reporting. Included on every plan.
Flags when your GTM container ships a GA4 ID that no longer matches your property.
Flags events firing in GTM with no matching key event configured in GA4 — invisible to Google Ads.
Flags multiple tags emitting the same event — the classic cause of double-counted purchases.
